How did frank capra and john ford interact with the star system?

dP/dt = (0.831 - 0.2P) / 100, where P represents pressure (in kilopascals).

This equation represents the rate at which the pressure is changing with the given conditions of temperature and volume.

To find the rate at which the pressure is changing, we need to use partial derivatives. Given the equation PV = 8.31T, we can differentiate both sides of the equation with respect to time t.

Differentiating both sides with respect to time t, we get:

P(dV/dt) + V(dP/dt) = 8.31(dT/dt)

Now, let's substitute the given values:

dT/dt = 0.1 K/s (rate of temperature change)

dV/dt = 0.2 L/s (rate of volume change)

T = 300 K (temperature)

V = 100 L (volume)

Plugging in the values into the equation:

P(0.2) + 100(dP/dt) = 8.31(0.1)

0.2P + 100(dP/dt) = 0.831

Now, we can solve for dP/dt:

100(dP/dt) = 0.831 - 0.2P

dP/dt = (0.831 - 0.2P) / 100

Therefore, the rate at which the pressure is changing when the temperature is 300 K and increasing at a rate of 0.1 K/s, and the volume is 100 L and increasing at a rate of 0.2 L/s is given by:

dP/dt = (0.831 - 0.2P) / 100

Answer:

The restoring force is Gravity.

Explanation:

In their most basic sense, waves are disturbances that travel through a medium, usually without the permanent displacement of the particles of the medium.

They are generally classified by the disturbing force that causes the wave and the restoring force that returns the water to normal once it has passed.

For example, the disturbing force for wind waves is usually wind and the restoring force is gravity.

Wind provides energy to the water, creating ripples and waves that travel across the surface of the water.

Gravity then acts to restore the surface of the water to its original state, pulling the water back down into the trough of the wave.

As the wave moves through the water, the water itself does not travel with the wave but instead moves in a circular motion, with the circular motion decreasing in size as it moves away from the wave.

This motion of the water is known as an orbital motion, with water particles moving in a circular motion but not traveling with the wave itself.

Explanation:

The net force on particle q2 can be calculated by finding the net electric force acting on it. The net electric force acting on a particle is the vector sum of the forces exerted by all the other charges on it.

The electric force between two charges q1 and q2 is given by Coulomb's law: F = k * (q1 * q2)/r^2, where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

The force on particle q2 due to q1 will be:

F1 = k * (q1 * q2) / (0.980m)^2

The force on particle q2 due to q3 will be:

F2 = k * (q2 * q3) / (0.750m)^2

The net force acting on q2 will be the vector sum of F1 and F2.

Keep in mind, q1 and q3 have opposite charges, so they attract each other, while q2 has the same charge as q1, so they repel each other.

Note: The unit of charge is Coulomb (C), but in this problem you are given the charges in microCoulomb (uC) so you need to convert it to Coulomb.

Answer:

If the ball is accelerating down through the air with no horizontal motion, the net forces acting on the ball must follow: C. The gravitational force is greater than the drag.

Explanation:

This is because the gravitational force is directed downward and the drag force opposes the direction of motion (therefore the drag force is directed upwards).  Since the ball is accelerating downwards, the gravitational force must be greater than the drag force in order to create this acceleration.

We know that the other options are incorrect because if the net force on the ball was directed upwards, the ball would be accelerating upwards.  If the net force on the ball was zero, the ball would not be accelerating at all.  If the drag was greater than the gravitational force, then the ball would be accelerating upwards as well.

The aquifer transmissivity is approximately 5,500 ft^2/day.

The drawdown in the observation well located 125 feet away is the difference between the head above sea level (277 ft) and the thickness of the aquifer (28 ft), which is 249 ft.

The drawdown in the observation well located 385 feet away is the difference between the head above sea level (291 ft) and the thickness of the aquifer (28 ft), which is 263 ft. Since there is no change in drawdown with time, this means that the cone of depression has reached a steady state, and the drawdown is constant.

The transmissivity of the aquifer can be calculated using the formula: Transmissivity = (Q / 2π) * (ln(r2/r1) / (s2 - s1)), where Q is the pumping rate (78,000 ft^3/day), r1 and r2 are the distances from the pumping well to the observation wells (125 ft and 385 ft respectively), and s1 and s2 are the drawdowns in the observation wells (249 ft and 263 ft respectively). Plugging in these values

we get Transmissivity = (78,000 / (2π)) * (ln(385/125) / (263-249)), which is approximately 5,500 ft^2/day.

Explanation:

The range of the electromagnetic spectrum that is less susceptible to interference from sources of visible light is the radio frequency (RF) range. Radio waves have much longer wavelengths than visible light, ranging from meters to kilometers, whereas visible light has wavelengths on the order of hundreds of nanometers. Due to the significant difference in wavelengths, the propagation and behavior of radio waves differ from visible light waves.

Interference from visible light sources, such as artificial lighting or sunlight, is typically confined to the visible spectrum and nearby infrared wavelengths. These sources emit electromagnetic radiation with shorter wavelengths, which can be absorbed, scattered, or reflected by various materials, causing interference. In contrast, radio waves can often penetrate through obstacles and are less affected by most common materials. They can travel longer distances and even diffract around objects, which makes them less susceptible to interference from visible light sources.

However, it is important to note that although radio waves are less susceptible to interference from visible light, they can still experience interference from other sources, such as other radio signals, electrical equipment, or atmospheric conditions. The specific susceptibility to interference depends on factors such as frequency, power, and environmental conditions.

Answer:

The length of the load arm is 3 m

The length of the effort arm is 15 m

Spoons and scissors are class 1 levers

Explanation:

The data given in the force diagram of the lever (machine) are;

The length of the lever = 18 m = (Length of effort arm) + (Length of load arm)

The force applied at the effort = 100 N

The load lifted by the lever = 500 N

The mechanical advantage, MA is given as follows;

MA = Load/Effort = (Length of effort arm)/(Length of load arm)

∴ MA = 500 N/(100 N) = 5

Let 'x' represent the length of the effort arm, and let 'y', represent the length of the load arm, we have;

x + y = 18...(1) (given)

MA = 5 = x/y

∴ x = 5·y...(2)

Substituting the value of 'x' in equation (1) with x = 5·y gives;

x + y = 5·y + y = 6·y = 18

∴ y = 18/6 = 3

y = 3

The length of the load arm, y = 3 m

x = 5·y = 5 × 3 = 15

x = 15

The length of the effort arm, x = 15 m

When lifting food with a spoon, the fulcrum, which can be taken as the edge of the plate or the supporting finger, is in between bowl of the spoon and the point of application of the thumb towards the extremities of the spoon handle

Therefore a spoon is a class 1 lever

The pivot of a scissors is in between the item being cut (the load) and the holes where the finger applies an effort

Therefore, a scissors is a class 1 lever.

The acceleration of the cart is 1.962 m/s^2, and the angular velocity of the wheel after 3 seconds is 11.772 rad/s.

To solve this problem, we need to find the net force acting on the cart and its acceleration using the principle of linear momentum. Then, we can use the principle of angular momentum to find the angular velocity of the wheel.

First, we find the center of mass of the cart and its load. Using the formula for the center of mass,

xG = (m1*x1 + m2*x2 + m3*x3 + m4*x4 + m5*x5) / (m1 + m2 + m3 + m4 + m5)

  = (100*0 + 100*1.2 + 100*0.5 + 50*0.3 + 50*0.4) / 300

  = 0.7 m

Next, we can find the net force acting on the cart by analyzing the forces acting on it. We have the weight of the system acting downwards, and the normal forces at A and B acting upwards. Since the cart is not accelerating vertically, the net force in the y-direction must be zero. Therefore, the normal forces at A and B are equal to the weight of the system, which is:

N = 1000 N

To find the net force in the x-direction, we use the principle of linear momentum:

F_net = m*a_G

     = 100*a_G

where a_G is the acceleration of the center of mass. Since the forces acting in the x-direction are the force of friction acting backwards, and the force of tension in the rope acting forwards, we have:

F_net = T - f

where T is the tension in the rope, and f is the force of friction. Since the wheel is rolling without slipping, we have:

f = (1/2)*m*g

where g is the acceleration due to gravity. Also, the tension T is equal to:

T = m*a

where a is the linear acceleration of the wheel.

Using the principle of rotation, we have:

I*alpha = T*r

where I is the moment of inertia of the wheel about its center of mass, alpha is the angular acceleration, and r is the radius of the wheel. Since the wheel starts from rest, its initial angular velocity is zero, and we can use the equation:

omega = alpha*t

to find the angular velocity after time t.

Substituting the given values, we have:

I = m*k^2

 = 100*(0.5)^2

 = 25 kg*m^2

r = 0.5 m

f = (1/2)*m*g

 = (1/2)*100*9.81

 = 490.5 N

T = m*a

F_net = T - f

     = m*a - (1/2)*m*g

F_net = m*a_G

     = 100*a_G

I*alpha = T*r

omega = alpha*t

Substituting T and alpha from the above equations, we get:

m*a*r = m*a - (1/2)*m*g

I*alpha = m*a*r

omega = alpha*t

Solving these equations, we get:

a = 1.962 m/s^2

alpha = a/r = 3.924 rad/s^2

omega = alpha*t = 11.772 rad/s

The cart and its load have a total mass of 100 kg with the center of mass at G. To determine the acceleration of the cart and the normal reactions on the pair of wheels at points A and B, we need to consider the forces acting on the system.

Since the cart's total weight is 100 kg and the gravitational force acting on it is 9.81 m/s², the weight W can be calculated as W = mass × gravity, which is W = 100 kg × 9.81 m/s² = 981 N. This force is acting vertically downwards at the center of mass G. Next, we need to consider the normal reactions on the pair of wheels at A and B. Let NA and NB represent the normal reactions at points A and B, respectively. These forces act vertically upwards, and for the cart to be in equilibrium, the sum of the forces in the vertical direction should be zero. Thus, NA + NB = W = 981 N. To determine the acceleration of the cart, we would need additional information about the forces acting in the horizontal direction, such as friction or an applied force. Without this information, it's not possible to calculate the acceleration of the cart. Regarding the 100 kg wheel with a radius of gyration (kO) of 500 mm, if it starts from rest, we need to determine its angular velocity after 3 seconds (t = 3s). However, we cannot calculate the angular velocity without knowing the torque or angular acceleration acting on the wheel. Additional information is needed to solve this part of the problem.

According to field theory, consensus is not a driving force that affects the development of a group. Instead, it is a result of the group's development and is influenced by other forces, such as the roles of group members and the ability of members to influence each other through power.

Field theory is a psychological theory developed by Kurt Lewin that explains how individuals and groups interact with their environment. Lewin believed that behavior is determined by the interaction of personal and environmental factors, and that groups are dynamic systems that are constantly changing.

In field theory, a group is conceptualized as a field of forces. These forces can be either driving forces, which push the group towards its goals, or restraining forces, which prevent the group from achieving its goals. Equilibrium forces, on the other hand, maintain the status quo.

The development of a group is influenced by a number of factors, including the roles of group members, confrontation in the group, and the ability of members to influence each other through power. The roles of group members refer to the functions and responsibilities that each member has in the group. Confrontation in the group refers to the conflict that arises when members have different opinions or goals. The ability of members to influence each other through power refers to the influence that members have on each other due to their personal traits, status, or skills.

Answer:

Explanation:

Potential energy is basically the build up of energy before it's released.

The voltage drop across the 18 kΩ resistor is 90 volts. This means that when a current of 5 mA flows through an 18 kΩ resistor, there is a potential difference of 90 volts across the resistor.

To calculate the voltage drop across a resistor, Ohm's Law can be applied. Ohm's Law states that the voltage (V) across a resistor is equal to the product of the current (I) flowing through it and the resistance (R) of the resistor. The formula for Ohm's Law is V = I * R.

Given:

Current (I) = 5 mA = 5 * 10^(-3) A

Resistance (R) = 18 kΩ = 18 * 10^(3) Ω

Using Ohm's Law, we can calculate the voltage drop (V):

V = I * R

= (5 * 10^(-3) A) * (18 * 10^(3) Ω)

= 90 V

Therefore, the voltage drop across the 18 kΩ resistor is 90 volts. This means that when a current of 5 mA flows through an 18 kΩ resistor, there is a potential difference of 90 volts across the resistor.
